SPOILER: Significant Others

Question: Any Castle news? —Gabriella Ausiello: “It’s every man’s worst nightmare,” show boss Andrew Marlowe explains, when Castle’s ex-wife Meredith (Scandal‘s Darby Stanchfield) not only resurfaces in the next new episode (airing Jan. 7), but crashes at his place to tend to a sick Alexis. Especially since Kate is also at the time bunking with Rick, who famously has/had a habit of indulging in “ex sex” — and old habits perhaps die hard for one of the former marrieds. ”Castle has kind of dug his own grave and spends the episode trying to dig himself out of it,” Marlowe previews. “It’s also interesting to see everybody else’s take on things.” For in addition to RySposito sounding off on the sticky sitch, “You have Lanie saying to Beckett, ‘Girl, you have got to claim your territory!’”

When a powerful divorce attorney who only represented women is murdered, Castle and Beckett are confronted with a plethora of angry ex-husbands, any one of whom could be the murderer. Meanwhile, Castle’s ex-wife (Darby Stanchfield, “Scandal”), Meredith, moves into the loft to take care of Alexis while she recovers from Mono, and to make matters worse, Beckett is also forced to move in while her apartment is being fumigated, causing tension, humor and more than a little awkwardness.
